Well last season the Prostar had a ton of issues. Main ones being exhaust manifolds and risers were shot, severe oil pan gasket leak, tranny cooler wasted, 60% of the motor was automotive (alternator, carberator, ect...)
So when the head bolt cracked the head. A gem was found a the perfect time (divine intervention?). The Prostar now has Seamaxx 5.8L HO 351 w (GT40 heads) w/ FWC system and Stainless steel manifolds. Ohhh Yeahh!
